What is the solution for oil burning in the second-generation EA888 engine?

If it is the second-generation EA888 engine, the phenomenon of oil burning is difficult to completely resolve as it is a common issue. You can try replacing the oil separator with the improved version from Volkswagen's original factory and switch to 5W40 or 0W40 engine oil that meets Volkswagen's 502/505 standards. After these changes, the situation should improve significantly. Methods to prevent oil burning are as follows: Method 1: Use engine oil that meets the technical requirements specified for the vehicle. Many car owners never check the vehicle manual and, after years of driving, still do not know what quality and viscosity grade of oil their vehicle requires. There is a lot of randomness in oil usage. When using engine oil, pay attention to both quality and viscosity indicators. The quality indicator means choosing SL grade or higher, and the viscosity indicator must strictly follow the specifications in the car manual—neither too low nor too high. Method 2: Avoid frequent rapid acceleration and prolonged high-speed driving. When the engine runs at very high speeds, it can easily break the lubricating oil film, leading to poor lubrication and dry friction in rotating parts. If this becomes a regular practice, it can cause abnormal engine wear and result in oil burning. Therefore, maintaining an economical speed is one of the best ways to prevent oil burning. Method 3: Ensure the engine oil is filled according to specifications. If the oil level exceeds the midpoint, ask the mechanic to remove the excess oil. Additionally, check the oil level the next morning before driving for an accurate measurement. Method 4: If oil burning is detected, visit a repair station as soon as possible for inspection. If the issue is due to engine faults (such as poor piston ring sealing, leaking valve seals, or leaking cylinder gaskets), promptly visit a repair station for diagnosis and early repair.
I drove a Volkswagen equipped with the second-generation EA888 engine and often noticed excessive oil consumption. At first, I thought it was a minor issue, but a friend later pointed out that it could affect the engine's lifespan. I took it to a repair shop, and the mechanic said the main cause was a design flaw in the piston rings, allowing oil to seep into the combustion chamber and burn off. The solution was to replace the piston ring set or pistons and, if necessary, the PCV valve. I opted for a full minor overhaul, which cost me around a thousand bucks. Now, after driving for over half a year, the oil level stays stable, and I don’t need to top it up frequently. If you notice a similar issue, I recommend not ignoring it—fixing it early saves hassle and extends the engine’s life. Also, daily driving habits like avoiding short trips and sudden acceleration can reduce the burden and significantly improve overall vehicle condition.
